Title: Method for purifying self-polymerizable monomer
Inventor: HIRAI YASUYUKI
IPC: C07D207/452
Filed: 1991-08-23
Abstract: PURPOSE:To purify a self-polymerizable monomer to high purity under mild conditions with excellent productivity by removing impurities from the crude self-polymerizable monomer with a specific solvent. CONSTITUTION:A crude self-polymerizable monomer is dissolved in a nonaqueous solvent which is an organic halogenated hydrocarbon-based solvent (e.g. methylene chloride or chloroform). Another kind of nonaqueous solvent, e.g. an aliphatic saturated hydrocarbon-based solvent (e.g. pentane or hexane), compatible with the above-mentioned nonaqueous solvent and capable of selectively precipitating organic impurities dissolved in the nonaqueous solvent and a salt are added to the resultant solution. Water is subsequently mixed to extract and remove the impurities into the water. The formed precipitates and an organic layer are separated from the aqueous layer to recover the self- polymerizable monomer useful as a precursor for polymer compounds from the organic layer.

CONSTITUTION:A contact point member 6 is a metallic piece, the tip part of the member 6 is raised, bent in an L-shape, passed through a hole part 7 drilled in one scissor, and protruded to the inner surface of one scissor 3, and the tip of the tip part becomes a contact point 5. A round hole 8 is drilled in the middle of this metallic piece, and a shaft screw 9 fixed to the scissor is passed through the round hole 8 and protruded to the outer surface of the metallic piece. A nut 10 is screwed on the shaft screw 9, and the protruding quantity of the inner surface of the contact point 5 is adjusted by the nut 10. Since the metallic piece has a plate spring structure and excellent resiliency, the contact point 5 is supported by this metallic piece and resiliently displaced with small force. Since the contact point 5 contacts on the inner surface of the other scissor 3 and presses the scissor 3, as the reaction of this, pressure contact force acts on the intersection of edge ends 11 and 11 of edge parts 2 and 2 positioned forward from a hinge shaft 4.

Title: Transistor switching circuit
Inventor: ISHIMA TSUTOMU
IPC: H03K17/04
Filed: 1984-10-12
Abstract: PURPOSE:To limit only an excess reverse base current at abnormity and to detect a fault in the short-circuit mode between a base and an emitter by providing a reverse base current detecting circuit to a circuit from a positive electrode of a negative bias power supply to the emitter. CONSTITUTION:The base current is applied to a base (gate) of a switching transistor (TR)1 through a base current limit resistor 4 from a positive bias power supply 2 and a negative bias power supply 3 through the switching drive of drive TRs 5A, 5B. When the TR1 is normal, since the base-emitter has a diode characteristic, when the base potential is negative than the emitter potential, a reverse base current I2 hardly flows. If the base-emitter of the TR1 is short-circuit due to any cause, a reverse base current I2 depending on the resistance value of the resistors 4, 7 and the voltage of the engative bias power supply 3 flows. A potential difference across the resistor 7 caused by the current I2 is detected by a voltage comparator 9 to drive a relay 10 for fault detection. The relay 10 stops the operation of the device.

Title: Nonvolatile semiconductor memory device
Inventor: HARIMA KANICHI
IPC: G11C16/02
Filed: 1982-12-03
Abstract: PURPOSE:To perform assured writing in a short time by setting the reference input potential of a differential sense amplifier at a level higher by a prescribed value than the reference input voltage of a normal read-out mode when a write verify mode is read out in a writing mode. CONSTITUTION:A transistor (TR) 27 is connected between the gate of a dummy memory TR171 and a joint spot, and the TR of a program voltage detecting circuit 26 is selected so that a threshold value is equal to about 10V as a whole. In other words, the voltage of about 2V is generated at a point (c) if the voltage higher than 10V is impressed to a program power supply terminal 25. Thus the TR27 is turned on for a while. The potential of the point (c) is set at 0V with the 10V input voltage, and therefore the TR27 is turned off. In such a way, the TR27 is off in a normal reading mode. As a result, the 3V voltage is obtained at an output point (b) for the reference signal generating circuit. Then the TR27 is turned on for a while when the write verify mode is read out in a writing mode, and the 3.5V voltage is obtained at the point (b).
